As used herein, " decompression " is commonly referred to as the ambient pressure that pressure is less than linear wound 12, tissue site or treatment site under treating.Under most of situations, this decompression will be less than the present atmospheric pressure of patient.Selectively, decompression can be less than the hydrostatic pressure in tissue site.Unless otherwise noted, be gauge pressure in the value of this definite pressure.The decompression of carrying can be constant or (specification or random) that change, and can be carried continuously or intermittently.Be applied to the pressure of tissue site although term " vacuum " and " negative pressure " can be used to describe, be applied to tissue site actual pressure can more than with normally associated pressure of absolute vacuum.Consistent with the use at this, the increase of decompression or vacuum pressure generally refers to the relative minimizing of absolute pressure.

Closed dressing bolster 46 can be made up and soft polymer preferably of polymer.In an illustrative embodiment, closed dressing bolster 46 is the materials with the hardness of 50Shore A, but other materials and feature are possible.Closed dressing bolster 46 and bolster main body 50 can be made up of transparent material, and containment member 72 is the same, to allow from the color of a bit checking linear wound 12 of depressurized system 10 outsides, the depth, edge of wound or other features (seeing Fig. 6) of color.The variation of the change color of linear wound 12 or the depth of color can show the generation of infection or other problems, and this visual prompting provides Useful Information to health care supplier.Bolster main body 50 can be made up of for example soft polymer, the silicones of medical grade or the flexible closed bolster material of other suitable materials.That closed dressing bolster 46 can be extruded, pour into is molded, injection-molded, blown-moulding or formed by other manufacturing technologies." flexibility " represents to move and is enough to produce interior to closing force.

Now mainly with reference to figure 2, closed dressing bolster 46 be illustrated be formed on the second wall 55 of bolster main body 50 or diapire towards the multiple holes 64 on the second interior side or surface 49.Hole 64 is formed on core 66 times, and particularly near the centrage 68 of bolster main body 50.Show that the details in a hole 64 is shown in Fig. 3 C.The first wall 53 or roof and the second wall 55 are connected to form hollow region or center compartment 57 to separate relation.Mainly with reference to figure 2, hole 64 is convenient to, by bolster main body 50, decompression is transferred to linear wound 12 again.The additional hole of different pattern can be arranged in bolster main body 50 so that decompression to the transmission of patient's epidermis 16, and the transmission of particularly arriving linear wound 12.One or more holes, such as hole 65, can be formed on first side 47 of the first wall 53 of bolster main body 50.Enclosed member 52,54,56,58,60 and 62 illustrates on the second side 49 towards interior.Enclosed member 52,56 and 58 is the second sidepiece at core 66 at the first sidepiece of core 66 and enclosed member 54,60 and 62.

As being clearly shown that in Fig. 3 A and 3B, inclined surface 69 has the angle forming about vertically extending imaginary plane (for vertical in the direction shown in Fig. 2).The inclined surface 69 relative with surface 63 illustrates reference vertical plane 59 angulations 61 that form about the summit place at inclined surface 69.

In operation, in the time that needs are treated, closed dressing bolster 46 is placed on linear wound 12, and the core 66 on linear wound 12 approaches center wound area 45 simultaneously.If closed dressing bolster 46 is not manufactured the containment member 72 with application on the first side 47 in advance, containment member 72 is employed and exceeds closed dressing bolster 46 and prolongs 77 to form wing flap extension or drape beyond the region of objective existence on the first side 47 of closed dressing bolster 46 so.Drape beyond the region of objective existence prolongs 77 and is employed to provide fluid-tight between the epidermis 16 containment member 72 and patient with band stickup or binding agent 82 downwards." fluid-tight " or " sealing " represents to consider the specific decompression subsystem relating to and is enough to keep the sealing of reducing pressure at the position of needs.

Decompression subsystem 90 by decompression plug into body 100 be fluidly connected to sealing subsystem 70.Reduced pressure source 92 is activated, and produce decompression and by reduced pressure delivery conduit 98 by reduced pressure delivery to the body 100 of plugging into of reducing pressure.In the time starting, Reduced pressure source 92 causes that to sealing subsystem 70 and decompression closed dressing bolster 46 produces compression stress 42 by reduced pressure delivery.The geometry of closed dressing bolster 46 can make bending moment produce about core 66, thereby and cause enclosed member 52,54,56,58,60 and 62 produce downward and inside making a concerted effort (for shown in direction).This effect produces directing force, for example compression stress 42 or closing force 44.Can experience these power at linear wound 12 places or near linear wound 12.

Mainly, with reference to figure 2, the generation of closing force or compression stress is described in further detail.Each in inclined surface 69 between adjacent enclosed member 58 and 56,56 and 52,52 and 54,54 and 60 and 60 and 62 forms a part for the ridge of triangle, and each has summit: the first summit 67, the second summit 71, culminating point 75, the 3rd summit 83 and the 4th summit 85.In the time that decompression enters hole 65, center compartment 57 is evacuated until some or all in summit 67,71,75,83 and 85 run into the first wall 53.Decompression also therefrom 57 is carried by hole 64 between septum cordis, and decompression can provide compared with propelling summit, highland or make as possible the power that the angle associated with each summit is less.Because these are active one or more, enclosed member 52,54,56,58,60 and 62 is advanced towards centrage 68, and by the friction of the epidermis with respect to patient from enclosed member 52,54,56,58,60 and 62, on patient's epidermis, produce closing force.Along with the first wall 53 and the second wall 55 are depressurized traction and are pulled towards patient or in the direction of advancing from the first wall 53 to second walls 55, can produce compression stress.

Now main with reference to figure 4A, 4B, 4C and 4D, show another illustrative embodiment of closed dressing bolster 146.Closed dressing bolster 146 has the bolster main body 150 that is formed with the first enclosed member 152 and the second enclosed member 154.The 3rd enclosed member 156 and the 4th enclosed member 158 are also shown.Enclosed member 152 and 156 is being to form on first side of a side of central plane 168 or core or Part I 153, and can extend the longitudinal length of closed dressing bolster 146.Enclosed member 154 and 158 is being to form on Part II on the opposite side of central plane 168 or side 155.

Central channel district 157 can help bolster main body 150 in this region bending, because produced bending moment under decompression.Bending moment contributes to enclosed member 152,154,156 and 158 is pressed onto in patient's epidermis and directing force can be provided, compression stress and the closing force for example for example, guided towards center wound area (region 45 in Fig. 1).In this illustrative embodiment, about the intensity of extruding and easness from a material, for example silicones, has selected the shape of bolster main body 150, for example, and so that bolster main body 150 is subsided in a desired manner or move to produce directing force, compression or closing force.Closed dressing bolster 146 can by transparent or at least partly transparent material make so that closed dressing bolster 146 can help the color of a bit checking the linear wound below closed dressing bolster 146 of the system outside from utilizing closed dressing bolster 146, the depth, edge of wound or other features of color.

As shown at Fig. 4 A and 4B, pipe jointer 199 can be used for providing decompression to closed dressing bolster.Pipe jointer 199 is made according to size and is configured to be coordinated with the central channel district 157 on closed dressing bolster 146.Pipe jointer 199 is fluidly connected to reduced pressure delivery conduit 198, thus reduced pressure delivery is arrived to closed dressing bolster 146.Within hole 151 allows to reduce pressure and is delivered to closed dressing bolster 146.As shown in clear in Fig. 4 C, hole 164 can form the linear wound below decompression being delivered to help in a part for closed dressing bolster 146.

Now main with reference to figure 4C-4D, the generation of closing force or compression stress will be described in further detail.In this illustrative embodiment, bolster main body 150 is squeezed center compartment 123 and the multiple compartment of being pressed with.Six 111,113,115,117,119 and 121 in multiple compartments form on Part I 153.Center compartment 123 forms in abutting connection with central channel 157 substantially.Six 125,127,129,131,133 and 135 in multiple compartments form on Part II 155.In this embodiment, only center compartment 123 receives decompression and does like this by hole 151.

Multiple compartments, for example compartment 111,113,115,117,119,121,125,127,129,131,133 and 135, uses the first wall 139 (or roof), the second wall 141 (or diapire) and multiple reticular component (web member) 143 to form.Except the bottom part 145 of central channel 157 is designed to subside with respect to the shelf portion (shelf portion) 161 of center compartment 123 under decompression, multiple compartments provide intensity to subside with respect to the second wall 141 to prevent the first wall 139.It should be noted in the discussion above that the first enclosed member 152 and second enclosed member 154 is separated separates, and make and be configured to provide treatment tank 163 according to size.Treatment tank 163 can have dome-shaped otch (dome-cutout) 165 and inclined wall 167.The first enclosed member 152 forms on the first sidepiece about central plane 168, and the second enclosed member 154 forms on the second sidepiece about central plane 168.

In the time that decompression is transported to hole 151, decompression enters center compartment 123 and is transported in treatment tank 163 by hole 164.Decompression causes the bottom part 145 of central channel 157 to be subsided and the shelf portion 161 of contact center compartment 123.In addition, the traction of the decompression in treatment tank 163 inclined wall 169 toward each other.These active one or more bolster main bodys 150 that cause are about central plane 168 warpages or bending, thereby and advance enclosed member towards central plane 168.Multiple compartments preferably do not subside and continue to provide intensity.And, inside when decompression,, on the direction of advancing from the first wall 139 to second walls 141, while drawing closed dressing bolster 146, produce compression stress.
